  3. Although they give answers in the form of questions on the TV show, you do not need to do this. You do need to write your answers on your game board! Keep track of your score …Add points for correct answers!

  4. Distance/time graphs Speed/time graphs Calculating speed from graphs Anything goes Acceleration 100 100 100 100 100 200 200 200 200 200 300 300 300 300 300 400 400 400 400 400 500 500 500 500 500

  5. Acceleration for $100 • Velocity includes • Speed • Distance • Speed and direction • Speed and distance

  6. C. Speed and direction Back toGame

  7. Acceleration for $200 Acceleration is A change in time A change in speed A change in distance A change in velocity

  8. D. A change in velocity Back toGame

  9. Acceleration for $300 • Which is an example of velocity? • 35km/hr • 35km/hr west • 22km west • 22 hrs

  10. B. 35 km/hr west Velocity includes distance and direction. Back toGame

  11. Acceleration for $400 • A dog is running after a rabbit in a straight line. The dog is slowing down as it gets closer to the rabbit. Which best describes the dogs acceleration. • The dog is accelerating because its velocity is changing • The dog is accelerating because its velocity is not changing. • The dog is not accelerating because it is speeding up

  12. A. The dog is accelerating because the velocity is changing Back toGame

  13. Acceleration for $500 • A car is traveling at a constant speed but is accelerating. This can occur because • It is slowing down • It is speeding up • It is changing directions • All cars accelerate

  14. C. It is changing directions Back toGame

  15. Distance / Time graphs for $100 • The graph shows • Speeding up • Slowing down • Constant speed • At rest

  16. C. Constant speed since it is a linear line Back toGame

  17. Distnace/time graphs for $200 • The graph shows • Speeding up • Slowing down • Constant speed • At rest

  18. A. Speeding up because the slope is increasing Back toGame

  19. Distance time graph for $300 • The graph shows • Speeding up • Slowing down • Constant speed • At rest

  20. D. At rest Back toGame

  21. Distance / time graphs for $400 • During which time interval is the car traveling at the greatest speed? • 0-3 • 3-5 • 5-6 • 5-9

  22. C. 5-6 because the slope is the greatest Back toGame

  23. Distance/time graphs for $500 • Which object is moving at a greater speed? • Red because it has a greater slope • Blue because it has a greater slope • Red because it a smaller slope • Blue because it has a smaller slope

  24. B. Blue because it has a greater slope Back toGame

  25. Speed time graphs for $100 • The graph represents • Speeding up • Slowing down • Constant speed • At rest

  26. C constant speed Back toGame

  27. Speed / time graphs for $200 • The graph represents • Speeding up • Slowing down • Constant speed • At rest

  28. D. At rest Back toGame

  29. Speed/ time graphs for $300 • The graph at interval C represents • Speeding up • Slowing down • Constant speed • At rest

  30. B. Slowing down Back toGame

  31. Speed/time graphs for $400 • At what point is the object traveling the fastest? • 1s • 2s • 4s • 8s

  32. D. 8s To read the speed / time graph you just read the time on the y axis Back toGame

  33. Speed / time graphs for $500 • At which interval was the object traveling at a constant speed? • 0-3 hr • 3-5 hr • 5-6 hr • 6-9 hr

  34. B. 3-5 hrs Back toGame

  35. Calculating speed from a graph $100 • What is the speed of the object at 4 hr? • 200km/hr • 300 km/hr • 0 km/hr • 87.7 km/hr

  36. B. 300 km/hr To read a speed time graph you just read the speed on the y axis Back toGame

  37. Calculating speed from a graph $200 • What is the average speed for the trip? • 60 m/s • 25m/s • 15m/s • 10 m/s

  38. C. 15m/s You take the total distance/total time Back toGame

  39. Speed from a graph for $300 • What is the speed of the object at 1 s? • 20m/s • 10m/s • 0.2 m/s • 0.1m/s

  40. 20 m/s • You take the distance /time for that point Back toGame

  41. Speed from a graph for $400 • What is the speed from 6-9 hr? • 100 km/hr • 50 km/hr • Okm/hr • 900 km/hr

  42. 100 km/hr • You take the difference in distance/difference in time Back toGame

  43. Speed from a graph for $500 • What is the speed from 2-4 hr? • 17.5 km/hr • 15km/hr • 20 km/hr • 21.5 km/hr

  44. C. 20 km/hr You take the difference in distance/difference in time Back toGame

  45. Scienctific Investigation for $100 • What could explain the difference in time for the 3 trials? • There is no difference • Trial 2 had more gravity • Trial 2 the marble was pushed • There was different friction

  46. C. Trial 2 was pushed Back toGame

  47. Scienctific Investigation for $200 • How high will the dog have climbed after 40 sec? • 6cm • 10cm • 8cm • 12cm

  48. C. 8cm Back toGame

  49. Scienctific Incestigation for $300 • An object will float in water if • The density of the object is less than water • The density of the object is greater than water • Everything floats in water • Density has nothing to do with floating or sinking

  50. A. Density of the object is less than water Back toGame
